WINDOW-VENTILATOR. I

To all whom it may concern:

Be it known that I, EDWARD E. GOLD, a citizen of the United States, residing in the borough of Manhattan, city, county, and

a State of New York, have invented certain new and useful Improvements in Window- Ventilators, of which the following is a specification.

My invention relates to an improved ventilator for use with windows, and has for its object to produce a ventilating screen that may be easily applied in position when required and when not required may be easily detached; further to produce a device which is under the immediate and easy control of a person near to the window, who may be either sitting or lying, as in railway sleeping cars; further to provide a device which will admit light and a supply of fresh air,

while at the same time it will prevent entrance of rain, dust, snow, etc. Further to provide a screen which shall deflect the air entering the window from an individual seated or lying near the window and cause the same to pass upward and above such individual and prevent a draft striking the body of such individual while at the same time permitting free ventilation and passage of light.

My invention is particularly applicable to the ventilation of railway cars, although it is not limited thereto, and may advantageously *be applied to ventilation of any apartment having windows.

A desirable form in which my invention may be embodied is illustrated in the accompanying drawings, wherein,

Figure 1 is an elevation of my invention applied to a window; Fig. 2 is a plan view thereof, the window frame, etc., being shown in horizontal section; Fig. 3 is a longitudinal section of my invention partly broken away; Fig. 4: is an enlarged detail end view illustrating a possible addition; Fig. 5 is a longitudinal section of the casing, roller, end caps and spring, without the curtain; Fig. 6 is a vertical section illustrating the construction of the lower end cap. Fig. 7 is an elevation of one manner of applying my in vention to a car window. Fig. 8 is a vertical section on the line 88, Fig. 7, looking to the right.

According to the form of my invention Specification of Letters Patent.

illustrated, I provide a flexible screen which is mounted within a suitable casing which is adapted to be attached at one side of a window, and means are provided whereby the I curtaln may be extended horizontally across thewindow and be. held in position at the opposite side. The curtain is preferably provided with means whereby it fits snugly against the window sill to prevent the passage of any wind below the curtain. The casing is preferably made detachable from the window so that it may be removed when 5 not required. I

A spring-retracted curtain is preferably employed and the omission of the ratchets frequently employed, as in the Hartshorn shade rollers, keeps the curtains under spring tension when extended and holds the same taut.

My invention is particularly applicable to the ventilation of passenger cars, by reason of the fact that it is contained in a casing which may be detached from the supporting bracket, and that thereby such brackets, I which are of slight expense, may be attached to every window, and the ventilators may be applied to such windows as are designated by the passengers. Thereby a considerable saving will be accomplished by the company owning the car, as comparatively few ventilators will supply the entire car, whereas under ordinary circumstances a ventilator would be required for each window, and the ventilators are out of the way when not in use. i

The particular form in which my invention is illustrated in the accompanying drawings includes a screen or curtain A which is flexible, and for this purpose the material ordinarily employed for the curtains of passenger coaches is well adapted. This curtain is mounted within a casing B upon a spring roller (1. This roller is of the usual construction of such rollers, but is preferably employed without holding pawls. It may be constructed as illustrated in Fig. 5 with a barrel 0 having a spring socket 0 wherein is mounted a spring 0 which is secured to the barrel at one end and at the other end is secured to a stud c which is I held from rotation. The lower end of the casing B is closed by a cap D. .The casing 10 B is slotted at b (Fig. 4) to permit the passage of the curtain. The lower end cap D has a slot d (Fig. 6), the position of which corresponds to the slot Z), and the purpose of which is to enable the curtain A when extended to lie close to the sill E and prevent the passage of any draft of air, or of any dust, moisture or snow between the said curtain and the sill. The casing B may, if desired, be provided with a spring finger I) (Fig. l) extending throughout its length, adapted to press against the outside of the curtain A and prevent the entrance of dust, etc., into the casing. The casing is provided with a bracket foi holding the same to the window frame or other part, and this as illustrated comprises a plate F having two tongues f diverging from the plate F and suitably secured to the casing B. The other part/of the bracket comprises a plate G suitably attached to the frame-work and having converging lips 5] adapted to form a groove to receive the tongues f, and permitting the casing to be freely attached or detached by a longitudinal sliding movement. The tongue and groove are transverse to the curtain in its extended position so that the manipulation of the curtain has no tendency to displace the casing although the latter is freely removable by a movement in the transverse direction.

The lower cap D is preferably perforated at d and provides a bearing within which the gudgeon c" of the roller C may freely rotate. The opposite or upper end of the casing is closed by an end cap H. The slot 5 may be suitably located with reference to the bracket so that the curtain shall emerge freely therethrough. As illustrated, the bracket is attached to the window frame parallel with the window, but some frames will not permit this, and the bracket in such case might require to be attached to a portion of the frame at right angles to that shown, and in such case the slot would require to be difierently located.

'The end caps H and D are reversible one with respect to the other to permit the curtain to be inverted in position, so that the curtain may be extended toward the left or toward the right as desired. Means for extending the curtain and securing the same in extended position comprise a ring a by which the curtain may be grasped to be extended, and which is well. mounted upon a curtain bar a which may be perforated at a to receive studs 60 attached to the window frame and entering the perforations (a to hold the curtain in extended. position. The bar a will provide means whereby the curtain will be prevented from passing entirely within the casing B.

Means are provided for winding up the curtain spring and holding the same when it is wound. Such means take the form of a key I having winding handles '5. This key is slotted at 2' with a flat slot adapted to fit the projecting flattened end of the spring stud c and prevent said parts rotating rela tively one to the other. The key has wings 2' which fit against the projecting ends of the casing B, and have at i perforations which correspond to perforations b in the casing. The end cap H is provided with slots h which are in line with some of the perforations b and is in addition preferably perforated with screw-retaining perforations at 701. In winding up the spring the key 1 will be applied so that its slot 17 will receive the stud 0 whereupon the key will be turned by hand if desired until the spring is'properly wound. While the spring is in this position a screw J may be inserted through the perforations 2?, 6 or if desired a temporary instrument, as for instance a small nail, may be passed through the said openings. Preferably there will be four corresponding openings 7?, b and screws J will be inserted in two suchsets of perforations which are oppositely disposed. When such screws have been inserted the end cap H may be applied so that the slot in will pass over the body of screws J and the screws may then be tightened. If desired an additional screw may then be inserted through the openings 72, in the end cap H, whereby the said end cap may be held in place. It will be apparent that means are thereby provided whereby the end cap may be removed without disturbing the adjustment of the spring. The lower end cap D is held in place by suitable means, as for instance, screws (Z in the casing B.

In the embodiment of the invention illustrated in Figs. 7 and 8 where it is shown as applied to a passenger car, there is in each of the windows an inner lower sash K, an outer upper sash K, and a screen K of wire netting located in a plane between the two sashes and extending from the sill upward so as to cover the entire height of the opening which can be obtained by raising the inner sash. In a plane inside of the inner sash K is a curtain or shade K of flexible material, the upper edge of which is fastened to a spring roller at the top of the easement and which may be pulled clear down to the sill. The chief function of this curtain is to cut off the direct light of the sun. Even when pulled entirely down it does not shield a passenger sitting or lying near the window from the wind (supposing the sash to be up) because its vertical edges are free and the draft forces them inward and escapes into the car with no deflection except in a horizontal plane from a transverse direction to a longitudinal direction, that is, squarely into the face of the passenger. Except for the air thus admitted in a longitudinal direction the curtain or shade K cuts off all access of fresh air to the is located entirely on the inner longitudinal face of the casement and lies flat against such face so that it in no way interferes with the sashes and other devices within the casement, so that it is accessible and operable by a passenger without getting up from his sitting or lying position (which is not true of the shade rolled up at the top), and so that it shields the passenger at once and by a simple construction from wind which may enter through the manifold cracks left by the devices within the casement.

In the combination described a number of separate devices are provided each performing a single function preferably because operated independently of the others, the function of each being to partially or completely exclude some element of annoyance to the passenger. Thus the sash entirely excludes air; the dust screen substantially excludes only dust while admitting the desired air; the shade excludes the light while admitting air and the wind deflector excludes direct drafts or converts them into unobjectionable vertical currents while admitting substantially all the light and air desirable.

Numerous changes and modifications may be made in the illustrated device within the limits of the appended claims.
